Automatic Submersible Boat Bilge Water Pump 12v 1100gph Auto with Float Switch, 1-1/8" Outlet, Compact Marine Boat Yacht

Working like a champ...solid product at a good/fair price. Bought this one as a backup for the first one we bought last May (2025) that is currently working fine...just wanted a backup in case the first one had a problem while we were camping. NOTE...we are using this in a portable DIY sump plump box for our Anvil cargo trailer toy hauler/camper conversion (aka our Harley Hauler) to plump the water (gray water) from our sink up into the sewer opening at campgrounds that have full-hookups. Due to the cargo trailer conversion being lower to the ground than regular RV camper trailers, it's hard (most times) for the water to drain unless the drain plugs are much lower than the camper pads. I'd buy again in the future and would/will recommend to others.

Well it’s sucks,…..of course it’s supposed to! Works great. I bought a backup too just out of experience but still have not needed it.

I recently installed the Maxzone bilge pump on my boat, and I couldn’t be happier with its performance. The 1100 GPH flow rate is impressive and ensures that my boat stays dry even in rough conditions. The automatic float switch is a game-changer, activating only when needed and saving battery life. The pump is also durable and well-constructed, with a moisture-tight seal and ABS material that gives me confidence in its longevity. Maintenance is a breeze thanks to the detachable strainer base, which makes cleaning quick and easy. While it can be a bit noisy, the peace of mind it provides far outweighs this minor inconvenience. Overall, the Maxzone bilge pump offers excellent value for the money and is a must-have for any boat owner. Highly recommended!

Pros: - Price. Seriously that is a good price for an emergency pump. - Small size and light weight. - Decent GPH for such a small unit. 1100GPH is good but remember it will decrease significantly pumping up. - 12V capability makes it versatile. - Internal float switch. Saves you money. Cons: - The output port is an odd-ball size. I had to make an adapter using Flexible hose just to get it to a standard size. I think they should include some adapters to make this easier on people. (if you plan on using PVC) - Noisy but do you care? I guess that depends on how often it turns on and if you can hear it. - I with the lines were a bit longer. You can splice more line but you gotta seal it very well. - The specs here say 3M head, the book it comes with says 5M, but honestly it has a tough time at 2M. I can hear it really trying hard. I'm not sure how long it may last. We'll see and I will update my review. Based on what I am seeing now, I would recommend this as a backup pump only. BTW: If you have a Watchdog Emergency Sump system and your pump died, this will work as a replacement. You must cut the connector off the old broken pump and splice it to the lines of this pump but IT DOES WORK fine. It's a cheap emergency backup pump! That what I used it for.

Works great easy to hook up.

Added to my boat. Works well and easily connected.

Works great and just keeps on working. Like all of these types of pumps you need to make sure gunk does not clog the pump. I surrounded it with a fine wire mesh that kept the gunk out. Not sure how it would have held up without doing that. Two things can go wrong with bilge pumps, trash can get sucked up into the float and block its performance, second, debris can get pulled into the pump blades and trash the motor, thus you need a fuse installed. When I purchase an automatic pump I check it for defects. First to see if it runs, second to see if it shuts off when the float drops, then turn it over to see if it comes own. I suspect in most cases the pumps that have the negative review were either installed incorrectly, or the bilges were not kept clean.Great little pump for the money.

This is a cheap pump. I bought it 8 months ago and it failed while I was 30 miles offshore and almost sank my boat. Luckily I had a hand pump as backup.

strong pump with a good head of 2mts on our training craft. Auto pump feature is handy as it will automatically start pumping once water enters the space it is in.

Excelente relación calidad precio.

Great product, works just like described

Fast pump. Easy to install

Great product I love the auto on feature. Peace of mind when you’re leaving your boat at the dock for extended periods.
